Abstract
A collective component has a first region that intersects with a conductive film for external terminal electrodes in a break line in which break leading holes are arranged and a second region that does not intersect with the conductive film for external terminal electrodes in the break line. The plurality of break leading holes includes at least one extending break leading hole located so as to extend over the first region and the second region.
Claims13
A ceramic electronic component comprising:
- a ceramic element assembly that has mutually opposite first and second principal surfaces and first to fourth side surfaces that connect the first and second principal surfaces;
- and
- an external conductor on the first principal surface of the ceramic element assembly, wherein
- a plurality of recessed grooves on the first side surface which extend in a direction to connect the first and second principal surfaces and at least reach the first principal surface, wherein
- a first edge portion of the first principal surface, which contacts the first side surface, has at least two first regions in which an edge of the external conductor is located, and at least one second region which is located between two adjacent first regions and in which the edge of the external conductor is not located, and wherein
- the plurality of recessed grooves include at least one extending recessed groove disposed so as to extend over the adjacent first regions and the second region therebetween,
- wherein the external conductor comprises a first external conductor having an edge located in one of the at least two first regions and a second external conductor having an edge located in the other one of the at least two first regions, and wherein the first external conductor and the second external conductor on the first principal surface are independent of each other,
- wherein the ceramic electronic component constitutes a monolithic ceramic capacitor that includes a plurality of laminated dielectric layers and first and second internal electrodes that face each other across a dielectric layer, wherein the first external conductor is electrically connected to the first internal electrode, and wherein the second external conductor is electrically connected to the second internal electrode.
